To all fw'wm t may concern."

Be it known, that I4, NATHANIEL M. L11 DELL, a citizen of the UnitedStates, residing at Danville, in the county of Vermilion and State ofIllinois, have invented certain new and useful Improvements inPaving-,Machines,`of which the following is a specication.

My invention relates to paving machines, for laying bricks or blocksupon a road-bed, sidewalk or'the like, while not necessarily restrictedto this use.

An important object of my invention is to provide L machine of the abovementioned character, whichis adapted to simultaneously lay a pluralityof bricks or blocks constituting a row, upon a suitable bed orfonndatiomin a highly expeditions and convenient manner. l

A further obJect of the invention 1s to lprovidea machine of the abovementioned character, having means to propel it longitudinally along theroad-bed being paved, which means are adapted to press the brick orblocks into close relation.

. A further object of the invention is to provide a machine of theabovementioned character, the principal partsof which are operated bygravity.

:Other objects and advantages of the invention will be apparentduringthe course of the following description.

Specification of Letters Patent. f

Patented Aug. 20, 1918.

Application filed December 1, i917'. Serial No. 204,885.

Fig. `11 is a. fragmentary plan view of the rear axle and associatedelements,

' F ig.` 12 is a side elevationV of a brake mechanism carried by thecontrol shaft, and, Fig. 13 is an edge elevation of the same.

ln the drawings, wherein for the purpose of .illustration is shown apreferred embodi ment of my invention, the numeral 15 designates asupporting vframe as a whole, comprising sides 16, and forward and rearends 17 and 18, as shown. `Arranged near the rear end 18 is an axle 19,preferably formed square in cross section, toreciprocate within guidebrackets 20, Vwhich are rigidly secured to the sides 16.y The axle 19carries flanged wheels 21, rotatable thereon, and adapted to travel uponside forms or curbing 22, which thus serve asa track. As more clearlyshown in Fig. 11, a portion of the axle 19 is provided with worm-teeth23, to be engaged by a worm 24, rigidly secured to a rotatablevshaft 25.This shaft .is turned by a hand wheel 26. The shaft 25 is journaledthrough openings 27 in a casting 28 bound upon one bracket 20. It isobvious that means is provided to transversely shift the rear end of theframe 15, with respect to the rear axle 19. The function of thisconstruction is to provide means whereby the rear end of the machinemaybe arranged at an angle with respect to the curbing 22, as whenlaying .the bricks upon a curve.k As more clearly shown in Fig. l0, theforward end 17 of the frame is provided with a depending support orbolster 29, which is rigidlysecured thereto, and has pivotal connection,at 30, with a forward axle 3l, whereby the frame is adapted to tilt in avertical plane with relation to the axle. 'This axle is prevented fromswinging fin, ahorizontal plane with relation to the frame by dependingstops 32, which are rigidly secured to the frame, and arranged upon therear sideof the axle .31, to contact therewith; The forward axle 81carries hanged wheels 33 pivoted thereto, and adapted to travel upon thecurbing 22.

The numeral 34 designates vertical standardsor uprights, which arerigidly secured to vthesides 16 of the frame 15. The standard 311 to theleft of the machine, in Fig.

chine. The standard 34 to the right, in Fig. 2 is taller than thestandard 34 to the left. lDisposed inwardly of the standards 34 (seeparticularly Fig. 7 arey slidable bars 35, having elongated slots 36formed in the upper ends thereof,l to receive spaced guide elements orbolts 37, carriedby the standards 34. Means are provided to raise theslide bars 35, comprising cams 38, disposed beneath the lower endsthereof, to contact therewith. These cams are rigidly secured to theends of a rock-'shaft 39, extending transversely of the frame 15, andhaving its ends 'ournaled through the sides 16. As more clearly shown inFig. 1, a hand crank 40, is rigidly secured to the rock-shaft 39, toturn it. From the forego.- ing description it is' obvious` that when thecams are turned upwardly, they lwill raise the sliding bars 35, and whenthese cams are turned in an opposite direction, the slidin'g bars willmove 'down by gravity.' The vertically movable sliding bars 35 have atrough 41 rigidly secured to the upper ends thereof. This trough extendstransversely ofthe frame 15, at an 'angle with relation thereto, and isalso vertically inclined', with its lower end disposed at the Operatin:side of the machine, in proximity 4to the and crank or lever 40. y

The trough 41 has its upper portion provided with longitudinal Vverticalanges 42 and 43, whereby such upper portion is substantially U-'shapedin cross `sectio'n, and adapted for the reception of 'a brickY or thelike. The vflange l,42 extends longitudinally throughout theentire-length ofthe trough, while the lower portion of the ll'ang'e 43is provided with openings 4 4, forming spaced upstanding fingers orplates 45, as more clearly shown 4in Figs. 8 and 9. Arranged within thetrough 41 are rollers 46, carried by shafts 47 The shafts 47 are pivotedin openings in theflanges 42 and 43 and in the flange 42 and the spacedfingers 45. A stop element 48 is arranged in the lower end of thetrough. From the foregoing description it is obvious that I haveprovided a gravity operated feed conveyer, fory receiving the bricks,which 4travel longitudinally therein,

to provide a row of the same.

vThe numeral 49 designates aysupporting rod, having its ends secured tothe sides 16. This rod is 4incapable of moving longitudinally withrespect to these sides. -The rod 49 is horizontahl and extendstransversely of the frame 15 at an angle with Vrelation thereto and isdisposed in a vertical plane .parallel with the vertical. plane ofl thefeed conveyer. Pivotedupon the support rod 49 are arms 50 of a swingingtransfer-carrier 51. These arms 50v are of different lengths Vand yareapproximately ofV the same len' h as the corresponding standards 34 utsomewhat shorter, to allow them to Vswing under the feed conveyer. Thearms 5() have apertured heads .52, which pivotally receive the rod 49,and ethe'openings of'these heads are disposed in an angle with respectto the arms, which arms 20 are arranged parallel to the sides 16, whenin the horizontal position, as shown in Fig. 2. The outer ends of thearms 59 are rigidly secured to a bar 53, having laterally extending`arms 54, as shown lmore clearly in Filis. 3 and 4. The a'rms'54 are 'at'a right angle to the arms 50 and are adapted 'to be "swungl beneath theconve'yer trough 41. Rigidly securedl to the opposite ends of the arms54 is a plate 55, disposed at a right angle thereto,l andcar'r yingvspaced supporting elements or teeth 6 arranged at a right angle to theplatev55. rigidly secured thereto. Thev supporting elemei'its of teeth56 are adapted A'to pass within the openings44 and between the rollers46, when the transverse carrier is swung "to the upper position.

The numeral 57 designates a toothed quadrant, oneendil'of 'which isrigidly secured y'to the bar l53'. The `opposite end of the toothedquadrant is preferably formed integral with an arm 58, 'extendinginwardly and connected with the support rod 49. The arm y58 ispreferably pivoted upon the rod 49, 'but cannot move longitudinally withrelation thereto. yTh'e toothed quadrant 57 is arranged perpendicular'to the r'od 49.

4The toothed quadrant 57 is engaged by a gear 59 which, isri'gidlysecured to a control sha'ft 60. `This 'control shaft is journaledthrough stationary bearings 61, which are 'rigidly secured tothestandardsf34- The shaft y60 extends transversely `of the frame, aftan angle with relation thereto,fand is inclined, and this shaft 'isdisposed in horizontal and verticalv planes, which are 'parallel to thehopper 41. The 'control shaft 60, as more lclearlyl shown in Fig. 12, is'provided with a brake drum 62, which 'is rigidly secured thereto. Thisbrake drum is arranged upon the operating 'side offthe machine and risengagedby "a brake band 63, which 'is thrown intoand out of action` by amanually operated lever 64, having latch means 65, coacting with astationary quad- 'ra'nt 66. It is thus apparentthat'means are providedto i lock the control shaft against rotation. The brake 'drum "Of-has ahandle 67 lrigidly secured thereto, whereby the` shaft 60 may be turned.

AConnected with the Aforward ends of the arms 50 are cables 68,extending upwardly and passed about grooved )pulleys 69, iv-

oted to the standards l34, at 70. eThe ca les 68v have their rear endsconnected with weights 71, whicha're adapted to automa-tically swingthetransfer-carrier to the 'upper position, when released.

l provide brick o'r block removing land pressing mechanism, forcoperation with the transfer carrier. This mechanism comprises atransversely reciprocatory bar or head 72, disposed inwardly of and nearthe rear end 18. This bar is rigidly secured to reciprocatory rack-bars7 3 sliding within stationary guides 74. The bar 72 extends transverselyof the frame 15 and is parallel with the end bar 18. The rack-bars 74are engaged by toothed segments 75, which are rigidly secured to arock-shaft 76, extending transversely of the frame 15, and Ysuitablyjournaled through the sides 16. Any suitable means may be employed toturn the rock-shaft 76, and as an illustration of a means I show a lever77, which is rigidly attached to one end of the rock-shaft 76. Ifdesired, power operated means may be employed to turn the rock-shaft.

Rigidly secured to the transversely reciprocatory bar 72 are spaced rodsor' teeth 7 8, extending rearwardly therefrom, and operating withinopenings 7 9 formed in the end bar 18, and to be shifted rearwardlybeyond this bar, across and beyond the plate 55, when this plate is Ainthe lowered position, as shown in Fig. 4. The rods or teeth 78 are sopositioned that they pass between the supporting elements or teeth 56,and `function to push the bricks or the like olf of the plate 55.

The operationof the machine is as foln lows z The curbing 22 for theroad-bed is first laid, in the usual manner, and the machine placed uponthe curbing, with its flanged wheels traveling thereon as a track. Atthe starting end of the road-bed there is a stop or abutment againstwhich the first row of bricks may be rmly pressed. It is customary toarrange the bricks in stacks or piles, at suitable intervals along theroad-bed.

The feed conveyer including the trough 41 is now moved to the raisedposition, by swinging the lever 40 downwardly, and temporarily retainedelevated. An operator or operators now feed Vthe individual bricks intothe upper end of the trough 41, whereby they travel downwardly thereinby gravity, until the lowermost brick contacts with the stop 48. In thisway the entire conveyertrough 41 may be filled with a row of bricks. Thetransfer-carrier including the plate 55 is now moved to the upperposition, as illustratedV in Fig. 5, which is accomplished by theoperator swinging the lever 64 in the direction to release the brakeband 63, whereby the weights 71 automatically swing the transfer-carrierto such upper position. The brakes are again applied to temporarily lockthe transfer-carrier in the upper position. Vhile the transfer-carrierkis in the upper position, the lever 40 is swung upwardly, therebycausing the conveyer-trough 41 to descend, as illustrated in Fig. 6. Thesupporting elements or teeth 56 of the transfercarrier now engage andhold the bricks, out of contact with the rollers 46, as the supportingelements are now disposed above such rollers. It is thus apparent that arow of bricks is now being held by the transfercarrier which is adaptedto swing or lower thesame to and upon the road-bed. The lever 64 issuitably operated whereby the brake band 63 is sufliciently released topermit of a slow turning movement of the drums 62, whereby thetransfer-carrier may gradually descend to the horizontal position. Ifdesired, a starting movement may be imparted to the transfer-carrier byan operator turning the drum 62 by means of the crank 67. Assuming thatthe transfer-carrier has been shifted to the horizontal position andlocked therein by the brake mechanism, as clearly shown in Fig. 4, therow of bricks will be held upon the upperpsurface of the plate 55. Theremoving and pressing mechanism is now actuated, by swinging the lever77 forwardly, causing the bars 73 to move rearwardly. This rearwardmovement of the bars shifts the rods 78 rearwardly, which remove thebricks from the plate 55, and deposits the same upon the road-bed, :inproximity to the previously laid row, or the stop or abutment. The rowof bricks thus deposited are pressed into close relation to thepreviously laid row, by a continued rearward movement of the rods 78,and when such operation is completed, further rearward movement of therods 78 will serve to propel or feed the entire machine forwardly, aproper distance, to provide a kspace forwardly of the row of bricks lastlaid, for the'reception of the next row of bricks. It is thus apparentthat the mechanism which removes and presses the brick into a properclose relation, also serves to propel or feed the machine longitudinallyof the road-bed or curbing. The rods 7 8 are now shifted to the forwardinactive position, as indicated in Fig. 4, whereby the transfer-carriermay again be shifted to the upper position. The transfer-carrier istokbe constructed in a length for receiving and transferring a row ofbricks of the proper length, and the flange 43 terminates at or near oneend of the transfer-carrier, whereby the transfer-carrier can only, pickup axrow of bricks of a suitable length.` As soon as the row has beenpicked up by the transfer-carrier, and the transfer-carrier is swingingdownwardly, the bricks in the upper portion of the conveyer-trough 41beginto descend, and an operator placed near the lower end of theconveyer-trough may insert a bat in the lower end of theconveyer-trough, whereby the next row of bricks will break joint withthe row previously laid. i

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the sameand thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.
